At the Kearney Connection, the NEC interconnects with the former Lackawanna line passing below it, with connectors on both the north and south sides of the NEC for the use of NJT trains. The crossovers at Hudson (MP 8.6 from Penn Station/7.2 from the former terminal at Jersey City) are at the southwest end of the Waterfront Connection, which runs eastward from track 1 of the NEC to track 2 of the M&E at Meadows (MP 4.3 on that line). This track is used mostly eastbound on weekday mornings and westbound on weekday afternoons, with one reverse-commute trip in each direction. On weekends, Raritan Valley and North Jersey Coast Line trains to and from Hoboken run about every other hour.
At Hudson, the number of tracks rises to three (with speeds 60-20) and then four (with speeds 45-20) the line from Meadows Yard (the former Jersey City line) also trails in from the east and the PATH tracks come alongside to the south. There are also eight yard tracks at Hudson, used to store Amtrak MoW equipment, NJT equipment going to and from the NJT Meadowlands Maintenance Center, and Raritan Valley trains turning back to Newark Penn Station. The NEC and PATH lines turn gently towards the southwest, past the passenger station at Harrison (MP 8.3), across the Passaic River at the crossovers at Dock (MP 8.5), where speeds become 35-20, and into the passenger station at Newark Penn. (MP 8.8), with four island platforms serving six through tracks and two PATH tracks, where the PATH service ends (the tracks continue a half mole further, bridging over the NEC to reach a storage yard on the west side.).
An overhead bridge at the south end of Newark Penn Station once carried the former CNJ Newark Branch over the NEC, requiring the southbound PATH tracks to descend steeply at the south end of their platform on the upper level.From Newark, the NEC turns south-southeast, with speeds 70-20, past the overbridge carrying the tracks to the PATH storage yard, crossovers at Cliff (MP 9.7), and at Hunter (MP 10.5), where the NJT line departs to the southwest (a connection to the former Lehigh Valley), there is a passenger station for Newark Airport, and a line trailing in from the east side, passing under the easternmost line, carries the former Lehigh Valley freight line from Oak Island Yard.
